UNITED STATES PATENT OFFIC JOHN F. BLESSING, OF CHICAGO, ILLINOIS.

BOX-CARRIER.

T 0 all whom it may concern.

Be it known that I, JOHN F. Bnessrxc, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Box-Carriers, of which the following is a specification.

This invention relates to a device designed to be used in a box factory, mercantile establishment, and other places for the purpose of carrying one or more boxes from one place or part thereof to any desired point.

The object of the invention is to obtain a. device by means of which a single box, or a plurality of boxes forming a pile, may be picked up, by the person operating the machine and easily transported to a different location.

Further objects are to obtain a device which is easily handled by one person; which is durable, not liable to break or get out of order, economically made, and operative by a person not particularly skilled in mechanics.

In the drawings which accompany and form a part of this specification Figure l is a side elevation of a device embodying the invention. Fig. 2 is a top plan view of the device which is illustrated in Fig. 1.. Fig. 3 is a modification of the handle of the device. Fig. 4- is a vertical section on line l Tl of Fig. 2, viewed in the direction indicated by the arrows. Fig. 5 is a perspective of one end of the body and frame of the device. Fig. 6 is a perspective of one of the movable pick-up members of the device. Fig. 7 is a top plan view of a modification of the handle of the device; and Fig. 8 is a front elevation of the modification illustrated in Fig. 7.

A reference character applied to designate a given part indicates said part throughout the several figures of the drawings, wherever the same appears.

A is the body frame of the device.

B is the operating handle of body A.

C is the journal bearing of axle D. There are two or more journal bearings C.

E are wheels rotatably mounted on axle D.

F, F are shafts rotatably mounted on body A, in journal bearings. Shafts F, F are respectively provided with external screw threads the entire length thereof between their journal bearings.

Specification of Letters Patent.

Application filed April 14, 1913.

Patented Jan. 13, 1914. Serial No. 761,023.

G, G are frames which are respectively movably mounted on body frame A.

g], g are boxes on frames G, G, respectively, and said boxes are provided with internal screw threads which correspond with the threads on, screws F, F, and fit thereto, so that as said shafts are rotated in one direction said frames G, G, are forced to approach each other, and when said shafts are rotated in the opposite direction said frames are forced apart,that is, turning the shafts F, F in one direction causes frames G, G to move from the position illustrated by full lines in Fig. 2 to the position indicated by broken lines H, in said figure, and turning said shafts in the opposite direction moves said frames from the position indicated by said broken lines H to the position in which they are illustrated by the full lines. The exact position of said frames G, G, is, of course, determined by the number of times said shafts are rotated.

it are what I term blades on frames G, G. These blades h are forced into contact with the box which is to be lifted and moved by the device, by turning the shafts F, F, as above described.

I, I are beveled gear wheels which are rigidly secured on shafts F, F.

J is a shaft which is rotatably mounted in bearings K, L, and M is a beveled gear wheel on shaft J which is rigidly secured phereto to intermesh with said beveled gears N is a crank handle secured to shaft J to afford means to turn said shaft, when desired.

O are stakes which are removably set in sockets O, and said stakes are used to pre vent tipping over of a pile of boxes while the same are being moved by this device.

In the modification which is illustrated in Figs. 7 and 8 bearing P is substituted for bearing L, and said bearing is provided with the wings p, p, in which handles Q are mounted.

In the modification which is illustrated in Fig. 3 the bearing R is substituted for bearing L, and said bearing R is provided with handle S, shaft T, and crank U. t, t are beveled gears on shafts J and T, intermeshing, so that when shaft T is turned by handle U the shaft J is turned.

To use the device it is backed up to a box or to a pile of boxes and the crank handle of the device is turned to bring or force the blades h of frames G, G, firmly against said box or pile of boxes, (that is, the bot tom box of said pile) and the handle 13 is depressed, thereby lifting the box or pile of boxes from the floor and on to the device. The boxes are then carried on the device to the location desired and by raising handle B they are set on the floor. The crank handles are turned and the blades h retracted from the bottom box and the device removed therefrom.

It will be observed that the frame A consists of the side bars V and end bars X, X; and said end bars are secured together by the bolts X".

I claim,

1. A body frame provided with an axle and carrying wheels, a handle to said body frame, a rotatable shaft to said handle and frame, a handle to said shaft, movable frames on said body frame, screw shafts on said body frame and bearings on said movable frames fitting said screw shafts, and a connection between said rotatable shaft and said screw shafts to synchronously rotate said screw shafts on the turning of said rotatable shaft, all combined as set forth.

2. A body frame provided with an axle and carrying wheels, movable frames on said )ody frame, screw shafts on said body frame, bearings on said movable frame, said bearings fitting said screw shafts, beveled gears on said screw shafts, a handle to said body frame, a shaft jonrnaled to said body frame and to said handle, a beveled gear on said last named shaft adapted to intermesh with the first named beveled gears, and a crank handle to turn said shaft.
